In this approach, data models can be read as a sentence, with the entities as the nouns and the relationships as the verbs.įor example, we can group the “customer” and its relationship to/action concerning the “product.” In this case, the model represents that “a customer may buy one or more products” via a visual “story” that makes sense to the business. The use of icons and graphics help tell the “story” of the model and ultimately the story of the business. When gathering business requirements, for example, it’s often more effective to use a conceptual data model and be creative with its display, as shown below. The same mode of thinking can and should be applied to data models.Īlthough it may be tempting to always include fully realized and in-depth data models to paint the fullest picture possible, that will not resonate with all parties.
